The Nike Zoom Speed Trainer is an ultra-lightweight training shoe for the athlete that wants to be quick on his feet. The mesh upper with external welded TPU reinforcements provides breathability and enhanced support. The Zoom Air unit in the heel of the midsole offers a low-profile and responsive protection. This gives you more control through quick directional changes and makes you more explosive coming out of these types of cuts. The all-over, multi-surface traction pattern in the outsole is engineered based on the pressure patterns of the foot, so you have great control where you need it most. Wt. 9.3 oz.
